Clinical Trial Summary

The purpose of this pilot trial is to examine the feasibility and ease of use of monitoring by ClearSight in laboring and delivering patients with the intent to compare time-to-treatment of hypotension between conventionally monitored patients (Group CM) and those receiving HPI (Group CM + HPI) monitoring by ClearSight, in a population of healthy laboring women who receive epidural analgesia.


Description:

In a prospective study, we will achieve the following aims: To determine the feasibility and ease of use of the ClearSight monitoring system in the labor-delivery room (LDR) in detecting and monitoring hypotensive events post-epidural labor analgesia placement. To compare the Time-to-Treatment of hypotensive events between the conventionally monitored patients (Group CM) and those receiving HPI (Group CM + HPI) monitoring by ClearSight.

Intervention

Diagnostic Test:
ClearSight HPI Monitoring system
Continuous blood pressure monitoring for precision hypotensive event response
Standard of Care Blood Pressure Monitoring
Blood pressure (BP) monitoring using a conventional arm cuff and inflation after epidural anesthesia as standard procedure. Standard of care blood pressure monitoring includes measurement of blood pressure at the time of epidural test dose delivery, 3-minute cycles of BP monitoring for 30 minutes after epidural placement, and then BP monitoring every 15 minutes per existing clinical standards for at least 4-hours, or until delivery.

Outcome

Type Measure Description Time frame Safety issue
Primary Time-to-treatment of hypotension (minutes) The difference in time between diagnosis of hypotension and treatment by clinical staff between CM and HPI groups From epidural placement until 4-hours post-infusion start
Primary Ease of use by clinical staff Clinical nurse reports of ease of use of ClearSight device (likert scale 0 - 5) report at 4-hour post-infusion
Primary Ease of hypotension detection by clinical staff Clinical nurse reports of ease of hypotension detection using ClearSight device (likert scale 0 - 5) report at 4-hour post-infusion
Primary Satisfaction of ClearSight use by clinical staff Clinical nurse reports of satisfaction of use of ClearSight device (likert scale 0 - 5) report at 4-hour post-infusion
Secondary Total time in hypotension with mean arterial pressure (MAP) <65 mmHg (in minutes) Average number of minutes patients spent within hypotensive events for each group (CM and CM + HPI). Epidural placement to 4-hours post-infusion start
Secondary Nausea (Yes/No) Proportion of patients by group reporting nausea within 4-hours of post-epidural placement Epidural placement to 4-hours post-infusion start
Secondary Vomiting (Yes/No) Proportion of patients by group reporting Vomiting within 4-hours of post-epidural placement Epidural placement to 4-hours post-infusion start
Secondary Total phenylephrine, mg Average phenylephrine dose(s) given to patients in CM and CM+HPI groups Epidural placement to 4-hours post-infusion start
Secondary Total ephedrine, mg Average ephedrine dose(s) given to patients in CM and CM+HPI groups Epidural placement to 4-hours post-infusion start
Secondary Total intravenous fluids, mL Average volume of fluids given to patients in CM and CM+HPI groups Epidural placement to 4-hours post-infusion start
Secondary Total number of reported changes in fetal heart rate category (from healthy to deceleration or excelleration) Average number of Fetal heart rate decelerations noted within the CM and CM+HPI groups. Epidural placement to 4-hours post-infusion start
Secondary Fetal heart rate decelerations within 1 hour of initiation of ELA Proportion of patients who experience any fetal heart rate deceleration event [Presence (Yes) or absence (No)] within 1-hour of epidural placement. Epidural placement to 1-hour post-infusion start
